I prefered thier later look. They seemed to kind of let thier personalities shine through a little more. In the early days they are really dressed kind of simmilar. They obviously didn't all wear the same clothes but they were all going for the same look. Fast forward to the Dahlia tours and the Last Live.
Pata had a more laid back look, the kind of thing a person could walk down the street wearing without getting weird looks, Heath, well, he never really changed his look as far as I could tell, hide was wearing more clolorful outfits rather than the kind of dark clothes he wore in the earlier days along with the others, for the most part Toshi's look changed in a way simmilar to Pata's though he still wore some costumish clothing (those coats, that kind of victorianish shirt during some ballads) and Yoshiki dropped the make up, decided to stop cross dressing and started dressing a little more business like during interviews.
They really started looking more like individuals instead of all going for the "let's shock the hell out of people look". Though I really did like that look too.
